METHOD AND APPARATUS FOR PROCESSING RLC/ PDCP ENTITIES AT A USER EQUIPMENT IN A DUAL CONNECTIVITY SYSTEM

摘要

An objective of the present invention is to provide a method and apparatus for processing RLC/PDCP entities at a user equipment in a dual connectivity system; when an uplink radio bearer is reconfigured from a first uplink bearer type between a user equipment and a primary and/or secondary base station into a second uplink bearer type between the user equipment and the secondary and/or primary base station, an RLC entity of the user equipment performing corresponding processing; the RLC entity transmitting indication information to a corresponding PDCP entity based on the processing; the PDCP entity performing processing based on the indication information, and transmitting PDCP PDU data corresponding to the uplink radio bearer through RLC entity corresponding to the second uplink bearer type. Compared with the prior art, the present invention provides a method of how to process RLC/PDP entities at a user equipment when an uplink radio bearer is reconfigured from one type of uplink radio bearer to another type of uplink radio bearer, particularly when the split radio bearer is reconfigured into an MCG bearer or an SCG bearer.
